Kumite... is where I put on a pad helmet, gloves, footgear, shinguards and groin cup and then go get the crap kicked out of me by someone fifty pounds heavier. I have a tough time reworking that for philosophical discussion, unless you're in the Orcish Philosophy Guild--where, after the argument, counterargument, and counter-counterargument, they draw weapons and enter a melee, and may the gods grant victory to whoever is right.
